Abstract
The invention relates to a concrete sealing curing agent, and a preparation method and a construction method thereof, and belongs to the technical field of concrete repair. The sealing curing agent comprises a component A and a component B, and the component A comprises water-based terpene resin sol and propylene glycoldiglycidyl ether; and the component B comprises an active cementing material and 10-15 parts of expanded perlite. The component B is smeared on the surface of concrete, the component B has good compatibility with old concrete ground, the surface of the concrete is continuouslycoated with the component A, and the component A is prepared by adding water-based terpene resin sol and propylene glycoldiglycidyl ether on the basis of an existing sealing curing agent, and when the component A and the component B are used for repairing the old concrete, the sealing curing agent can be better combined with the old concrete into a whole, an originally loose honeycomb structure is filled to form a compact solid, water vapor, oil stains and the like are effectively isolated, and the compactness of the old concrete is improved, so the sealing curing agent has the sealing and repairing functions at the same time.
Description
technical field [0001] The invention relates to the technical field of concrete restoration, in particular to a concrete sealing and curing agent, a preparation method and a construction method thereof. Background technique [0002] Concrete sealing and curing agent is a colorless, odorless, non-toxic liquid sealant, which can fully chemically react with the chemical components in concrete and stonework through effective penetration to form a high-strength, high-hardness curing Floor, chemical reaction products can block the pores of concrete from the inside, so that the concrete is transformed into a solid and sealed whole, which effectively improves the strength and density of the floor, prevents dust, and at the same time carefully polishes the ground, which can make the floor The ground produces a higher gloss, which increases the aesthetic effect of use. [0003] At present, the popular concrete sealing and curing agents on the market can be roughly divided into two ca...
